Down syndrome (DS) is one of the most common causes of developmental delay. In India, there is no protocol for prenatal screening of DS. Second-trimester biochemical screening is still being done by triple test. Quadruple test is with better sensitivity and specificity but is not advised routinely. So, the objective of this study was to evaluate the sensitivity and accuracy of the second-trimester screening (quadruple test with genetic sonogram) for trisomy 21 as compared to biochemical testing.
